In order to consider the heat dissipation factor of the lamp, a cavity with heat dissipation fins is set on the mold, and a lamp holder with heat dissipation fins is prepared by die-casting. This processing method causes the position of the fins to be unable to be adjusted, and the heat exchange efficiency of the fins is affected by the surrounding environmental airflow. When the environment in which the lamp is applied is different, the spacing of the fins cannot be adjusted to optimize the heat dissipation route, resulting in the heat dissipation of the lamp holder not reaching the best effect. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem existing in the prior art that a cavity with heat dissipation fins is set on the mold, and a lamp holder with heat dissipation fins is prepared by die-casting. This processing method causes the position of the fins to be unable to be adjusted, and the heat exchange efficiency of the fins is affected by the surrounding environmental airflow. When the environment in which the lamp is applied is different, the spacing of the fins cannot be adjusted to optimize the heat dissipation route, resulting in the heat dissipation of the lamp holder not reaching the best effect, and to propose a lightweight die-cast aluminum LED lamp.

[0006] To achieve the above object, the present utility model adopts the following technical solutions: A lightweight die-cast aluminum LED lamp, comprising a lamp cover, a lamp top base, and a light bulb.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0014] 1. In the present utility model, when the lamp top base is die-cast, the cavities of the first guide groove and the second guide groove are arranged in the cavity of the mold, so that the first heat sinks and the second heat sinks are both distributed in a staggered manner in a radial shape.

[0022] In order to more clearly understand the above objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0024] Embodiment 1: As shown in Figures 1-5As shown in the figure, the utility model provides a lightweight die-cast aluminum LED lamp, which includes a lamp cover 1, a lamp top base 3 and a light bulb 5. The lamp top base 3 is provided with a first heat sink 8 and a second heat sink 9. The outer periphery of the lamp top base 3 is equally spaced with a first guide groove 10, and the inner periphery of the lamp top base 3 is equally spaced with a second guide groove 11. The first heat sink 8 is slidably connected to the first guide groove 10, and the second heat sink 9 is slidably connected to the second guide groove 11. The first heat sinks 8 are equally spaced along the outer circle of the lamp top base 3, and the second heat sinks 9 are equally spaced along the inner circle of the lamp top base 3. The first heat sinks 8 and the second heat sinks 9 are both distributed in a staggered manner in a radial shape.

[0025] The lamp base of the LED lamp is made of aluminum material. Since the aluminum material has a smaller density than other metal materials, the aluminum lamp can meet the lightweight design requirements of the lamp. When the lamp is powered on and working, the surface temperature of the lamp base gradually increases. In order to avoid damaging electronic components due to high temperature and improve the service life of the lamp, usually a heat sink fin is arranged above the lamp base, and the heat of the lamp base is transferred to the surrounding air in time by the heat sink fin. Generally, the heat sink fin is made by using a die-casting mold when the lamp base is die-cast. Not only can the position of the fin not be adjusted, but also the heat dissipation distance of the fin is the same. However, the heat exchange efficiency of the fin is affected by the surrounding ambient air flow. When the environment in which the lamp is applied is different, adjusting the distance between the fins to optimize the heat dissipation route can make a certain number of fins achieve the maximum heat dissipation effect.

[0026] In this embodiment, when the lamp top base 3 is die-cast, the positions where heat sink fins need to be originally arranged are redesigned as the first guide groove 10 and the second guide groove 11. After die-casting, the first heat sink 8 and the second heat sink 9 are respectively installed on the first guide groove 10 and the second guide groove 11, and then the distances between the first heat sink 8 and the second heat sink 9 are adjusted according to the use needs, and the distribution design of the heat sink fins is adjusted to improve the heat dissipation requirements of the lamp.

[0027] Embodiment 2: As Figure 3 and Figure 5 shown, a hanging ring 2 is fixedly connected to the top surface of the lamp cover 1. A wire connection base 4 is fixedly connected to the center position of the top end of the lamp top base 3, and the wire connection base 4 is connected to a power supply wire. A lamp connection base 6 is fixedly connected to the center position of the bottom end of the lamp top base 3. A sealing ring 7 is sleeved on the outer side wall of the lamp connection base 6, and the lamp connection base 6 is clamped at the middle position of the lamp cover 1 through the sealing ring 7. Double-hole ear seats 12 are fixedly connected to the opposite side walls of the first heat sink 8 and the second heat sink 9. A positioning seat 13 is arranged between the first heat sink 8 and the second heat sink 9. The bottom end of the positioning seat 13 is fixedly connected to the lamp top base 3, and the top end of the positioning seat 13 is rotatably connected to a connecting rod 14, and both ends of the connecting rod 14 are movably connected to the double-hole ear seats 12.

[0028] The effect achieved by the entire embodiment is that external threads are provided on the outer wall of the top end of the lamp socket 6, and internally threaded holes adapted thereto are provided in the middle of the lamp cover 1, so that the lamp socket 6 can be installed in the middle of the lamp cover 1. The upper part of the lamp cover 1 is connected to the power line, and a light bulb 5 is installed below the lamp cover 1 to provide illumination. In addition, a hanging ring 2 is provided on the outer side of the lamp cover 1. When the LED lamp is installed in a hanging manner, the hanging ring 2 can be connected to the ceiling at multiple points, reducing the connection pressure of the lamp and ensuring the stability of the hanging lamp. A plurality of positioning seats 13 are provided above the lamp top seat 3, and the heights of two adjacent positioning seats 13 are different, so that the heights of the connecting rods 14 are staggered from each other. Connecting double-hole ear seats 12 are provided inside the first heat sink 8 and the second heat sink 9. The two through holes of the double-hole ear seat 12 are respectively connected to the connecting rods 14 on both sides, so that the connection between the connecting rods 14 and the double-hole ear seat 12 surrounds a circle, forming a linkage of the positions of all the first heat sinks 8 and the second heat sinks 9. When adjusting the position of one of the first heat sinks 8, the other first heat sinks 8 and the second heat sinks 9 will move together. Move the first heat sink 8 inward, and using the lever principle of the positioning seat 13, the connecting rod 14 drives the second heat sink 9 to move outward, increasing the staggered area between the first heat sink 8 and the second heat sink 9 and extending the heat dissipation air flow channel formed between the first heat sink 8 and the second heat sink 9. Conversely, move the first heat sink 8 outward, and the connecting rod 14 will drive the second heat sink 9 to move inward, reducing the staggered area between the first heat sink 8 and the second heat sink 9 and shortening the heat dissipation air flow channel formed between the first heat sink 8 and the second heat sink 9.

[0029] The usage method and working principle of the present device: When adjusting the distribution of the heat dissipation fins and the design of the heat dissipation air flow channel, move the first heat sink 8 inward, and using the lever principle of the positioning seat 13, the connecting rod 14 drives the second heat sink 9 to move outward, increasing the staggered area between the first heat sink 8 and the second heat sink 9 and extending the heat dissipation air flow channel formed between the first heat sink 8 and the second heat sink 9;

[0030] Conversely, move the first heat sink 8 outward, and the connecting rod 14 will drive the second heat sink 9 to move inward, reducing the staggered area between the first heat sink 8 and the second heat sink 9 and shortening the heat dissipation air flow channel formed between the first heat sink 8 and the second heat sink 9.

[0031] The above is only a preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
